In ancient times the Incas fed an empire with marginal land utilizing sustainable farming techniques—even managing to store 3-5 years worth of extra food in case drought, hail or frost ruined a year's crops. Today, The Seedling Project is working to record current farming methods as passed down through generations.

Organic agriculture is a "good option for food security in Africa", UNCTAD says, citing a 116% rise in productivity on 114 African farms that converted to organic or near-organic production.

Truly, truly thrilling, and I especially love this line in the recommendations for government section: Fund research on sustainable agriculture, building on indigenous knowledge in response and in partnership with farmers. EXACTLY what needs to happen in Peru as well (and what our friends at Cusichaca were doing last I heard).
